10. The test can take a while to perform. First the EVCC300 will put the charger into a charging mode and
measure the output voltage.
11. The EVCC300 will then perform a touch voltage test. This is to ensure that the charger earth or ground will
not raise in voltage to a hazardous level during the actual RCD / GFCI test. There are two test limits that can
be applied to the touch voltage test, 25 V and 50 V. These are set in the instruments settings screen.
12. Finally, if the touch voltage test has passed the EVCC300 will
perform the chosen earth leakage current test. The test result
being displayed in mA.
5.5.3 Interpreting test results
a.
Mains (line) voltage test
Should the charger fail to switch the output voltage the test will stop
Check the charger connections and fuses
b.
Touch voltage test
Should the touch voltage test fail this will be because the charger either has no, or a poor, connection to the PE,
protective earth. Should this occur do not attempt to perform any more testing and consult a qualified electrician to
determine and rectify the fault.
